n64graphics_ci

Allows you to convert PNG image files to/from N64 CI format. This is temporary until queueRAM adds CI support into his official n64graphics tool. This tool does not process RGBA, IA, or I textures, use n64graphics for those.

CI4 textures will always assume a 16 color palette is used, and CI8 textures a 256 palette is used. The palette will be generated as a seperate file. The palette file will be named after the CI filename, but postpended with .pal.
